To all whom it may concern.-

Be it known that I, VICTOR POPP, a citizen of the Republic of Fran ce,residing at the city of Paris, France, have invented-certain new and useful Improvements in Automatic Oilin g Devices, of which the following is a specification.

This invention is embodied in patents in the following countries: In France, November 15, 1887, No. 186,828; in England, November 18, 1887, Nos. 15,878,15,878, and 15,878; in Germany, December 24, 1887, Nos. 44,745 and 47,546; in Belgium, May 7, 1888, No. 81,725, and in Italy, June 30, 1888, Vol. 46, No. 247.

My invention consists in an automatic oiling device for a motor operated by compressed air, steam, gas, or similar fiuid,whereby the oil contained in the exhaust-fluid may be recovered and automatically returned to the cylinder of the engine. It is illustrated in the ac companying drawings, in which- Figure 1 is avertical section of my apparatus. Fig. 2 is a horizontal section on the line 2 2, Fig. 1. Fig. 3 is a view of a detached filter. Flg. 4 is a horizontal section on the line 4 4, Fig. 8.

In Fig. 1,.A is the exhaust-pipe from a compresscd-air or similar motor. WVith the exhaust is carried a considerable amount of oil used for lubrication in the cylinder. The pipe A terminates in a chamber B, having walls of wire-netting and felt,which serves as a filter, retaining the oil and water from the air while permitting the air itself to escape.

C is a surrounding vessel of sheet iron or brass. At its lower part is a receptacle E, in which the oil is collected asit is slowly filtered through the walls of B, The upper portion of the receptacle E is formed with holes D for the escape'of air. 7

This apparatus constitutes my filter for exhaust-fluids, and it may be used alone, as shown in Fig. 3,where the whole apparatus is completely surrounded by the casing C,which in this case is provided with an outlet-pipe F for the air, a faucet U being provided for drawing off the oil from the receptacle E.

In Fig. 1 the filter is combined with an apparatus for automatically returning the collected oil to the cylinder of the engine.

11 is a closed vessel placed in receptacle E and communicating therewith through a valve K (it maybe of steel) inits bottom. The vessel H has legs lifting it above the bottom of receptacle E, so that the oil can readily circulate under it and up through the passage in the valve-seat K, the valve opening upwardly to permit the oil to pass.

L and M are two tubes entering the top of the vessel H, the latter being continued to a point near the floor of the vessel. The tube L is connected to a supply of compressed air or other actuating-fluid, while the tube M leads to the cylinder of the engine through the oiler O, which is provided with a regulatingvalve P and a glass Q, through which the flow of the oil may be observed.

In operation the compressed air entering by tube L exerts a pressure upon the oil con tained in vessel II and tends to force it out through the tube M into the cylinder of the engine through oiler O. The oil which is gradually collected in receptacle E forms a constant supply, which is forced into the vessel H through the valve K in the following manner: When the compressed air is shut ofi? fromthe engine, the piston will continue to operate for a short time on account of its momentum. This will cause it to act as a pump, tending to produce a vacuum in the tube M. This will cause the oil in receptacle E to rise under the pressure of the outside air through the valve K and fill vessel H. The action of the apparatus is thus perfectly automatic, the supply in receptacleE being constantly maintained by the dripping from filter 13, The vessel C is also open at its upper end, so that fresh oil can be readily added.

I claim- 1. The combination, with the exhaust-pipe 0 of a compressedair or similar motor, of a filter placed across the course of the fluid, and an adjacent receptacle for collecting the oil from the filter.

2. The combination, with the exhaust-pipe of a compressed-air or similar motor, of a chamber having walls of filtering material such as felt or wire-nettingand a receptacle for collecting the drippings from the filter formed by the said chamber.

3. The combination,with the exhaust-pipe of a compressed-air or similar motor, of a fil ter for collecting the oil, a receptacle for the oil, and a tube leading therefrom to a part of the motor requiring lubrication.

4. The combination,with the exhaust-pipe of a compressed-air or similar motor, of a filter'for collecting the oil, a receptacle for the oil, a tube leading therefrom to a point in the motor requiringlubrication, and a second tube connecting the receptacle with a supply of air or other liquid under pressure.

5. The combination,with the exhaust-pipe of a compressed-air 01' similar motor, of a filter for collecting the oil, a receptacle for the oil, a Vessel connected therewith through an intermediate check-valve, a tube leading from said vessel to a part of the motor requiring lubricatiolnand a second tube connecting the vessel with a supply of air or other fluid under pressure.

6. In an automatic oiling device, the combination,with a receptacle containing a supply of oil, of a vessel connected therewith through an intermediate check-valve, a tube leading from said vessel to a part of the motor requiring lubrication, and a second tube connecting the vessel with a supply of air or other fluid under pressure.

7. The combination,with exhaust-pipe A, of filtering-chamber B, inclosing-vessel C, terminating in receptacle E, a closed vessel H, placed in receptacle E, an intermediate valve K, a tube M, leading to the cylinder of a compressed-air or similar motor, and a tube L, connected with a supply of air or other fluid under pressure.
